MX213 PLC脈沖量的控制目的主要是位置控制、運(yùn)動(dòng)控制、軌跡控制等。例如：脈沖數(shù)在角度控制中的應(yīng)用。步進(jìn)電機(jī)驅(qū)動(dòng)器的細(xì)分是每圈10000，要求步進(jìn)電機(jī)旋轉(zhuǎn)90度。

那么所要?jiǎng)幼鞯拿}沖數(shù)值=10000/(360/90)=2500

PLC編程算法(2)——模擬量的計(jì)算

1、 -10—10V。-10V—10V的電壓時(shí)，在6000分辨率時(shí)被轉(zhuǎn)換為F448—0BB8Hex(-3000—3000);12000分辨率時(shí)被轉(zhuǎn)換為E890—1770Hex(-6000—6000)。

2、 0—10V。0—10V的電壓時(shí)，在12000分辨率時(shí)被轉(zhuǎn)換為0—1770Hex(0—6000);12000分辨率時(shí)被轉(zhuǎn)換為0—2EE0Hex(0—12000)。

3、 0—20mA。0—20mA的電流時(shí)，在6000分辨率時(shí)被轉(zhuǎn)換為0—1770Hex(0—6000);12000分辨率時(shí)被轉(zhuǎn)換為0—2EE0Hex(0—12000)。

4、 4—20mA。4—20mA的電流時(shí)，在6000分辨率時(shí)被轉(zhuǎn)換為0—1770Hex(0—6000);12000分辨率時(shí)被轉(zhuǎn)換為0—2EE0Hex(0—12000)。

以上僅做簡(jiǎn)單的介紹，不同的PLC有不同的分辨率，并且您所測(cè)量物理量實(shí)現(xiàn)的量程不一樣。計(jì)算結(jié)果可能有差異。
